Effect of Resonant Continuum on Pairing Correlations in the Relativistic Approach

We have investigated the pairing correlation for neutron-rich Ni isotopes in the relativistic mean field theory (RMF) and Bardeen-Cooper-Schrieffer approximation. There are a few resonant states with life times in the continuum. A proper treatment of the resonant state in the continuum on pairing correlations has to include not only its energy, but also its width.
